Nuclear Power

NEOTISS has been a trusted supplier to the global nuclear power industry for over four decades. We supply high-performance welded tubes for condensers, high-pressure and low-pressure feedwater heaters, and moisture separator reheaters (MSRs) in nuclear power plants on every continent.

Condensers

The surface condenser is a key factor in plant performance. Its primary function is to condense the exhaust steam from the low-pressure turbine and return the feedwater to the steam generator or boiler. The cooling water can flow from either a closed- or open-loop system, making the condenser a critical component — raw water ingress can contaminate the chemically controlled steam/water loop.

Products & Solutions

Condenser tube materials:

• Titanium Grade 2
• Stainless Steel — 304, 304L, 316, 316L, 317L, 2205, LDX2101
• Super Stainless Steel — AL6XN®, 29-4C®, 254SMO®, 2507

Condenser tube designs: Smooth or NEOTISS™ Helix — Straight

LP & HP Feedwater Heaters

Low-pressure and high-pressure feedwater heaters extract steam from the low- and high-pressure turbines to heat the feedwater from the condenser and forward it to the primary loop of the boiler or steam generator. The intelligent use of this energy source is critical for the overall efficiency of the power plant.

Products & Solutions

Low Pressure FeedWater Heater tubes:

• Material: Austenitic Stainless Steel — 304, 304N, 304L, 316, 316L
• Design: Smooth & U-bent

High Pressure FeedWater Heater tubes:

• Material: Ferritic Stainless Steel TP439
• Design: Smooth & U-bent

MSRs — Moisture Separator Reheaters

The MSR is a key component in the steam cycle of nuclear power plants. By removing moisture from exhaust steam leaving the high-pressure turbine and reheating the dry steam before entering the low-pressure turbines, it increases the overall efficiency of the nuclear steam supply system and protects low-pressure turbine stages from moisture damage.
